Abstract
Relay auto-tuning of linear PID regulators is now a proven technology in the process control industry. In this paper it is extended to auto- tune nonlinear PID controllers for unsymmetrical processes. Two sets o f PID parameters, each for one operating mode, are obtained with a sin gle relay experiment. Excellent performance of the auto-tuned nonlinea r control system is substantiated by simulations. (C) 1998 Elsevier Sc ience Ltd.
